My mom (divorced & 77) is very ill in S. Carolina; death imminent. Until 2 weeks ago, she was lifelong resident of Illinois, location of her condo & personal property. On 6/3/13, we had her medically evacuated to SC so brother & sis-in-law could oversee her care; constant travel to IL got too stressful. I, her daughter, live in TX and am her POA. I've been handling her affairs since April 2013. Her 1986 will names me Executrix and brother & I are named as equal beneficiaries of her estate. On her death, won't probate need to be filed in IL? She never established SC residency, apart from her very ill body being in a SNF -- now hospital -- bed there for the past 2 weeks. IL condo is in her name (no mortgage) & has to be sold. Bro & I named beneficiaries on all her IRAs, life insurance, etc.
