The purchase conveyancing process in the UK is the legal process of transferring ownership of a property from the seller to the buyer. It typically involves several stages, including:

1. Instructing a conveyancer: The buyer and seller each appoint a qualified conveyancer, who will handle the legal aspects of the transaction on their behalf.
2. Exchange of contracts: The buyer and seller agree on the price and terms of the sale and sign legally binding contracts. At this stage, the buyer usually pays a deposit.
3. Searches and enquiries: The conveyancer will conduct various searches and make enquiries to ensure that the property is in good condition and that there are no outstanding issues, such as planning permission or building regulation compliance.
4. Preparation of the transfer documents: The conveyancer will prepare the necessary documents to transfer ownership of the property, including the transfer deed and mortgage deed (if applicable).
5. Completion: The final stage of the process, the buyer pays the remaining balance of the purchase price and the conveyancer will complete the transfer of ownership. The keys will be handed over to the buyer.
6. Registering the property: Once completion is done, the conveyancer will register the new ownership at the Land Registry.

The whole process usually takes between 8-12 weeks, but it can take longer if there are any complications. It's important to have the right professional help, such as a solicitor or licensed conveyancer, to ensure the process runs smoothly.
