A construction lawyer reviews your contract legally: clauses, compliance with standard terms legislation and liability risks. An online quote review assesses the commercial aspects: prices, completeness and variation risks. A commercial online review is sufficient for most renovation projects. For legal disputes or complex contractual arrangements, a specialist construction lawyer is the more sensible choice.
Key points at a glance
- A construction lawyer checks clauses, compliance with standard terms legislation and liability risks — costing 149–850 € depending on provider and scope
- An online quote review analyses prices, completeness and variation risks — from 79 €, with results in 24h to 4 working days
- Both approaches complement each other: for large projects with complex contractual clauses, a combination of commercial and legal review is recommended
What does a construction lawyer check?
A solicitor specialising in construction law analyses your contract from a legal perspective. Since the reform of construction contract law in 2018 (§§ 650a to 650v BGB), special protections have applied to consumer construction contracts, and a construction lawyer can specifically check compliance with them.4 The focus is on which clauses are enforceable, which breach statutory requirements and where you, as the project owner, are legally disadvantaged.
Typical areas checked by a construction lawyer:
- Contract law: Review under BGB (§§ 631 ff., §§ 650a ff.) and, where applicable, VOB/B, identifying unfavourable provisions and unenforceable clauses
- Standard terms review: Reviewing general terms and conditions under §§ 305 to 310 BGB, particularly unreasonable disadvantage within the meaning of § 307 BGB. The German Bar Association (DAV) points out that standard terms in construction contracts are particularly frequently subject to judicial review.5
- Liability clauses: Checking limitations of liability, exclusion clauses and their enforceability in consumer contracts
- Contract drafting: Recommendations for drafting or renegotiating specific clauses to strengthen the project owner's legal position
- Defects liability and acceptance: Checking the legal enforceability of agreed periods and conditions
Cost: A solicitor's construction contract review costs between 149 and 850 euros depending on provider and scope. Online platforms such as yourXpert offer reviews from 149 to 189 euros; established platforms such as Wohnglück charge around 850 euros. Independent construction lawyers charge between 250 and 500 euros per hour, depending on the firm and region.1
Turnaround: Simple online reviews by solicitors are completed within a few hours to a few days. Independent law firms or complex contracts may take considerably longer.
Note: A construction lawyer cannot and is not permitted to give you a commercial assessment of market prices, quantities or the completeness of the quote. This falls outside the scope of legal review.
What does an online quote review check?
An online quote review such as Cleverbauen24's starts at a different point: it analyses the construction quote from a commercial and construction-technical perspective. The question is not whether clauses are legally enforceable, but whether prices are reasonable, services are missing and variation risks are hidden.
Typical areas covered by an online quote review:
- Price plausibility: Comparing quoted unit prices against regional market prices, identifying conspicuously excessive items or those involving estimating risks
- Completeness check:Checking whether all essential work is included or whether commonly problematic items (e.g. waterproofing, disposal, site setup) are missing from the quote
- Variation risks: Analysing which missing or unclear items could be billed as variations during the project
- Market price comparison: Assessing quoted prices against current reference prices for the relevant trade and region
- Calculation check: Checking quantities, unit prices and totals for arithmetic errors or inconsistencies
- Contractual issues: Flagging problematic payment schedules, missing defects liability provisions or unclear specifications, without providing legal advice within the meaning of the RDG
This review therefore fills the gap left by a construction lawyer: you learn not only whether the contract is legally sound, but whether the contractor's charges are also fair in the market.
Cost: Basic review 79 euros (3 to 4 working days), Express review 99 euros (24 hours).
Turnaround: 1 to 4 working days, depending on the chosen plan.

Cost comparison
The table below shows what a construction contract review costs by provider and which review scope is included:
| Provider | Cost | Turnaround | Review scope |
|---|---|---|---|
| yourXpert (online solicitor) | 149 to 189 euros | 4 hours to 10 days | Construction contract only (legal) |
| Wohnglück (solicitor) | 850 euros | 5 working days | Construction contract only (legal) |
| Independent construction lawyer | 250 to 500 euros/hour | Days to weeks | Contract and negotiation (legal) |
| Cleverbauen24 | 79 euros (Basic) / 99 euros (Express) | 3 to 4 working days / 24 hours | Quote and contract (commercial) |
The price difference between the options is considerable, but their service scopes are fundamentally different. A solicitor checks whether the contract stands up legally. An online quote review checks whether prices and services are commercially fair. The two are not mutually exclusive.
What can a solicitor do that an online review cannot?
There are services a construction lawyer provides that no review service can replace, because they are legally reserved for solicitors:
- Legal advice: A binding legal assessment of whether a clause is enforceable, with the solicitor personally liable
- Contract drafting: Drafting alternative clauses or complete contract drafts that are legally sound
- Court representation: Enforcing claims in disputes, formal warnings, interim injunctions, legal proceedings
- Standard terms review under §§ 305 ff. BGB: Binding assessment of whether general terms and conditions withstand judicial scrutiny
- Out-of-court settlement: Solicitor-led negotiations with the contractor to amend the contract or settle damages
Cleverbauen24 is not a legal services provider within the meaning of the Legal Services Act (RDG) and may not provide legal advice.6 Comments on legal issues in quotes are informational and not legally binding.
What can an online review do that a solicitor cannot?
Conversely, a construction lawyer does not typically focus on technical and commercial construction questions:
- Market price comparison: Assessing quoted prices against current reference values for the specific trade in the relevant region
- Item analysis: Checking all individual items for accuracy, consistent quantities and technical construction plausibility
- Quantity check: Checking whether stated quantities match the described scope of work and whether there are arithmetic errors
- Completeness check: Identifying missing services that could be charged as variations during the project
- Industry knowledge: Using experience from comparable projects to assess what is realistic in terms of price and service
Construction lawyers who can also answer technical construction questions are rare. This is generally a matter of training: lawyers assess contract law, while engineers and experienced reviewers assess prices and services.
Decision guide: solicitor or online review?
The choice depends on where your risk lies and exactly what you want to know:
| Situation | Recommendation |
|---|---|
| You want to know whether the price is fair | Online quote review |
| You want to know whether services are missing | Online quote review |
| You want to assess variation risks | Online quote review |
| You have a disputed clause in the contract | Construction lawyer |
| You want the contract legally secured | Construction lawyer |
| There is already a dispute with the contractor | Construction lawyer |
| Large project, high value (> 150.000 euros) | Both worthwhile |
| Renovation with a contractor (15.000 to 80.000 euros) | Online quote review |
In many cases, a solicitor and quote review are not mutually exclusive. A commercial review is often the sensible first step. If it reveals specific legal issues, the next step is a construction lawyer. Find guidance on common variation traps in our guide Avoiding variation costs.
Provider comparison
Here is an overview of the common options for reviewing construction quotes and contracts, with current prices:23
| Provider | Cost | Turnaround |
|---|---|---|
| Independent surveyor | 360 to 714 euros | 2 to 4 weeks |
| Consumer advice centre | 180 to 370 euros | 1 to 3 weeks |
| VPB | 175 euros+/hour | by arrangement |
| Cleverbauen24 | from 79 euros | 3 to 4 days (Basic) / 24 hours (Express) |
An independent surveyor and the VPB are particularly suitable for complex major projects or when an expert opinion is needed for legal disputes. Consumer advice centres offer independent advice, but with longer waiting times. A digital quote review such as Cleverbauen24's is the quickest and most affordable option for mid-priced renovation projects.
Frequently asked questions
How much does it cost for a solicitor to review a construction contract?
Costs depend heavily on the provider. Online platforms offering solicitor reviews (e.g. yourXpert) charge 149 to 189 euros. Specialist providers such as Wohnglück charge around 850 euros. Independent construction lawyers charge hourly, between 250 and 500 euros depending on the firm and region. For a substantial contract, a solicitor's review can quickly cost 500 to 1.500 euros.1
Do I need a solicitor for my construction contract?
Not necessarily. For a typical contractor-led renovation project, a commercial quote review is generally sufficient. According to the Verband Privater Bauherren (VPB), fewer than 30 per cent of private project owners have their contracts professionally reviewed before signing.7 A construction lawyer makes sense if the contract contains unusual clauses, if a conflict with the contractor already exists or if the project value is so large that legal risks could have substantial financial consequences.
What is the difference between a solicitor's review and a quote review?
A solicitor's review assesses the contract legally: clauses, general terms, liability and enforceability of provisions. A quote review assesses the quote commercially and technically: prices, completeness, variation risks and quantity plausibility. The reviews complement each other, while their subject matter is not mutually exclusive.
Can an online review replace a solicitor?
For commercial questions yes, for legal questions no. Cleverbauen24 is not a legal services provider and may not provide legal advice. A quote review answers whether a price is fair and services are missing. Anyone wanting to know whether a clause is legally unenforceable needs a solicitor. The Bauherren-Schutzbund (BSB) recommends both a commercial and a legal review for contract values of 100.000 euros or more.8 In many projects, a quote review is the more sensible first step.
When should I involve a construction lawyer?
A construction lawyer is the right contact if you have specific legal questions about contractual clauses, a defects dispute arises after acceptance, the contractor submits variations you consider unjustified or you want to enforce a damages claim. Before entering into a contract, a construction lawyer is particularly important if it contains standard terms you cannot assess or the project is unusually large.

Comments
It would never have occurred to me that specialist online services for reviewing construction contracts exist. Interesting comparison.
A specialist construction lawyer charged me 850 euros to review a contract — but it was worth it in the end because he found two really problematic clauses.
For standard contracts, I'd lean towards an online service. For anything with a contract value of half a million euros or more, I'd rather go to a lawyer.
Where does a quote review end and a construction contract review begin? I have both documents and am unsure which to have checked first.
Good question! Start with the quote — because it defines the scope that then feeds into the contract. If the quote has shortcomings (unclear items, missing work), these should be resolved before you sign. Then check the contract text itself for the legal clauses.
