What happens at this stage
Solicitor goes through search results and enquiries. You agree a completion date, sign the contract, and send the deposit. Then solicitors swap signed copies — legally binding.

- 1Negotiate a completion date that works for the whole chain.
- 2Arrange CHAPS payment to your solicitor (banks limit normal transfers).
- 3Sign and return the contract — your solicitor will brief you.
Watch out for
- Buildings insurance not active from exchange day.
- Chain wobbles in the final week.
- Forgetting completion date is now contractually fixed.
