Most construction disputes are not about dishonesty. They are about two people who each believed something different was agreed, and who never wrote it down clearly enough to check.

A good agreement is not a defence against a bad builder. It is a way of finding out, before work starts, whether you and your builder actually understand the project the same way. If the document is hard to write, the disagreement already existed — you have just found it early, which is the cheapest time to find it.

Here is what a construction agreement should cover.

1. The parties, and who signs

Full legal names of both parties. If you are appointing someone to sign on your behalf, the authority for that should be clear and documented.

Note that the builder's legal entity name may differ from the brand name you know them by. That is normal, but the agreement should name the legal entity.

2. Scope of work

The heart of the agreement. It should describe what is being built, and — just as importantly — what is not included.

Vague scope is the most expensive thing in any contract. "Complete construction of residential building" is not a scope. A scope names the stages, the extent of each, and the exclusions.

3. Specifications

What materials, what brands or grades, what fittings, what finishes. Where specifications are not yet chosen, the agreement should state an allowance and how the final choice affects the price.

This is where "the quote was lower" usually gets explained. Two quotes for the same house with different specifications are not comparable.

4. Drawings

Which drawings the agreement is based on, by number and date. Construction against undated drawings means nobody can later establish what was agreed.

5. Price, and the basis of it

The total, and how it was calculated — per square foot or as a complete project. If per square foot, exactly how the area is measured. Area measurement conventions vary, and a difference in method can change the total significantly.

Whether taxes are included or additional should be stated explicitly.

6. Payment schedule

What is paid when, and against what. Payment tied to stages completed protects both parties better than payment tied to dates.

Be cautious of front-loaded schedules where a large share is due before meaningful work exists on site.

7. Timeline

Start date, expected completion, and the stage schedule in between.

Also: what happens if it runs late, and what causes are treated as legitimate reasons for extension. No agreement can promise that nothing will delay a project. A good one says how delays will be communicated and managed.

8. Change requests

How changes are proposed, priced, approved and recorded.

The key principle is simple: no change proceeds without written approval. If your agreement does not say this, add it.

9. Quality standards and inspection

What standards the work will meet, and your right to inspect — or to have someone inspect on your behalf.

10. Approvals and permissions

Who is responsible for obtaining which approvals, who bears the cost, and what happens if an approval is delayed or refused.

11. Site responsibilities

Who provides water and power during construction, who secures the site, who is responsible for materials stored there, and who is liable for workers on site.

12. Handover

What condition the property will be in, what documents you receive, and what constitutes completion.

Snagging matters here: how defects identified at handover are recorded and rectified, and by when.

13. Post-handover support

What is covered after handover, for how long, and what is excluded. This varies considerably between builders — do not assume, and do not rely on a verbal assurance.

14. Termination

What happens if either party needs to stop. How work completed is valued, and how materials on site are dealt with.

Nobody expects to use this clause, which is exactly why it is often missing.

15. Dispute resolution

How disagreements are resolved, and where. Agreeing this while everyone is on good terms is far easier than agreeing it later.

What to watch for

  • Scope described in a single sentence. Ask for it in stages.
  • "As per standard practice." Whose standard? Written down where?
  • Specifications listed as "best quality" or "branded." These are not specifications.
  • No change process. This will cost you.
  • Payment schedules ahead of progress.
  • Verbal assurances not reflected in the document. If it matters, it goes in the agreement.

Finally

Have the agreement reviewed by a lawyer before you sign, particularly if you are signing from outside India. This article describes what agreements generally contain; it is not legal advice, and it cannot account for your circumstances.
