Date of closing and possession
A typical real estate contract specifies a date by which the closing must occur. The closing is the event in which the money (or other consideration) for the real estate is paid for and title (ownership) of the real estate is conveyed from the seller(s) to the buyer(s). The conveyance is done by the seller(s) signing a deed for buyer(s) or their attorneys or other agents to record the transfer of ownership. Often other paperwork is necessary at the closing.
The date of the closing is normally also the date when possession of the real estate is transferred from the seller(s) to the buyer(s). However, the real estate contract can specify a different date when possession changes hands. Transfer of possession of a house, condominium, or building is usually accomplished by handing over the key(s) to it. The contract may have provisions in case the seller(s) hold over possession beyond the agreed date.
The contract can also specify which party pays for what closing costs. If the contract does not specify, then there are certain customary defaults depending on law, common law (judicial precedents), location, and other orders or agreements, regarding who pays for which closing costs.
