The remainder of the purchase price needs to be with solicitor in readiness for legal completion to take place on the specified completion date. The period between exchange at the auction and completion is usually 28 days, but you should always check in advance as the period may be shorter or longer. There may be charges that also become payable on completion; please speak with your solicitor for advice and ensure you have sufficient funds to settle the full purchase price and any disbursements. Your solicitor will guide you through this process.
