Of course, such behavior has legal effect.

Husband and wife * * * with a will means that after discussion, husband and wife agree on the same property and deal with the property after death by the same will. The establishment of husband and wife's * * * same will is based on the * * * same meaning of both husband and wife, and the object of will disposition is the husband and wife's * * * same property.

There is no explicit provision in China's Law of Succession for husband and wife to have the same will, but there is no prohibition. Therefore, according to the legal principle of "the law is feasible without prohibition", both husband and wife can dispose of their * * * property in the form of a will. Here, it should also be noted that after the death of one party, the living party has no right to make a will instead of the deceased.

if the husband and wife don't know how to write or set up the same will, they can come to a lawyer and ask them to provide reasonable advice. ?
