1. The lease contract of the house where one party lives outside;
2. The written agreement on the separation of husband and wife signed by both parties must be in writing, and the oral agreement must be acknowledged by the other party;
3. The written separation document sent by one party to the other party should preferably be sent by express mail, with "separation" indicated in the remarks column, and the mailing certificate kept.
