What does Completion mean?

Pertaining to property law, completion is a phase by which the buyer becomes the rightful owner of a property. Completion occurs only after the lender makes the buyer’s solicitor eligible to have access to the entire funds needed, which actually means the whole legal path required for buying a property has come to a good end.
The buyer becomes the rightful owner (title holding) after the amount of money is received by the seller’s solicitor.
