You will need to bring a government issued ID when you attend a closing. Some lenders require two forms of IDs, so please bring a second form of identification to be safe.
If you are receiving funds from a sale or refinance, and you would prefer a wire instead of a check, you should bring your wire instructions (verified by your bank) with you to confirm with your attorney.
Lastly, when buying or selling real estate, it is a good idea to coordinate with your real estate agent about the transfer of keys, key fobs or garage door openers in order to avoid confusion after closing.
