Question: Can my wife or husband witness my signature?Answer:
Usually, your wife or husband should not witness your signature. Whether or not you can witness a signature depends on the nature of the agreement that you are witnessing. Usually, it is best practice to have a third party witness your signature. You should particularly not witness a signature where your wife or husband is a party to the agreement. If you are signing a deed, a third party should witness your signature and again they should not also be a party to that agreement.
