W was put into a position of becoming successor trustee over her mother’s trust and executor of her S’s estate in 2016.
Your sister will have to obtain a federal tax id (employment identification number or EIN) to open an estate checking account. Banks won’t’ open estate checking acct without an EIN…S can’t use her or your dad’s SSN for estate checking acct. Talk to new attorney/CPA about process, it’s pretty easy, can be done online.
All monies from dad’s accts before death, or from sale of personal and real property, life insurance, etc should go into estate checking acct. Don’t commingle money from dad’s monies with your or sister’s personal accts. While waiting for monies to come in (eg sale of property), your sister should talk with attorney if she needs to advance her own funds to estate checking to pay incoming bills (eg utilities on real property… MIL’s house was in somewhat cold climate and required heat/electricity to be kept on so house stayed warm/ pipes didn’t freeze)). When time came to settle estate/trust, W as trustee/executor was first to be paid back… advancing of funds was considered an administrative expense and had high priority, meaning W was first in line to be paid.
Your sister should keep meticulous financial records. Hopefully your sister is good with keeping track of income/expenses, balancing a checkbook. Hopefully sister and you can play nice. One thing lawyer advised W was to keep her other sister informed. Every month W sent out detailed accounting/summary of all actions that W had taken in past 30 days. W would call sister and they would discuss/clarify monthly summary/accounting. It made for a very smooth sailing when W wrapped up both estates.
Hopefully mess with attorney is straightened out quickly as even when ducks are in a row, probate process tends to drag out. Good luck.
