The Remove Spouse option removes the spouse/partner, but keeps the spouse/partner’s record independently.  There is a System Option, named Balances to Primary on Split, that dictates how historical transactions will be assigned during this process.  

Setting this to True indicates that all transactions conducted by the couple will be assigned to the primary account holder. 

Setting this to False indicates that transactions will be assigned based on the party to act on the transaction.  Here are the scenarios:

• If the transaction is a sale only, it stays with individual who conducted it.
• If the transaction has an intake step such as in repairs, special orders, custom jobs, appraisals, layaways, and memos, and no activity occurs on that transaction by the primary account holder, then the transaction stays with the individual. For instance, a repair intake is done by the spouse/partner and pickup is done by primary, that sale will go to the primary account holder.
• If it is a house or credit transaction, the sale will remain with the individual.
• Any house or credit or sales activity on a sale the changes to the primary account holder will also be assigned to the primary account holder.

NOTE:  The anniversary and spouse/partner’s birthday will remain; it you want that removed, do so manually.
