The activity log, at the bottom of each asset or debt, is used to record transfers from the deceased’s accounts to the estate accounts and to record payments and distributions to beneficiaries.
Update the current market value of each asset or the outstanding balance of each debt before logging the activity.
The asset and debt activity logs provide dual tracking, meaning that if you transfer money from one of the deceased’s accounts into an estate account, the transaction shows in 2 places: as a debit in the deceased’s asset and a credit to the estate account.
If you transfer money from the estate bank account to a beneficiary, the transaction shows as a debit in the estate account and a credit in the beneficiary’s distribution record (described below).
Partial or full payments of debts works the same way: the payment is debited from the estate bank account and credited to the mortgage account.
The onus is on you to double check that the numbers are correctly reported on both sides.
