Mr. Sobchak and Ms. Kish were dating. Since they had both been married before and each had an adult child, they decided to keep their finances separate, and they each maintained their own residences. They each had wills leaving their estates to their children. As they got older, Ms. Kish developed dementia and Mr. Sobchak became her caregiver. Mr. Sobchak then became ill and passed away recently, after which his girlfriend's son sued Mr. Sobchak's estate saying that Ms. Kish was a spouse and was entitled to support from the estate.
The court found that despite their intentions, their behaviour indicated that they were spouses. Fortunately, the court also found that the greedy son would not get anything from Mr. Sobchak's estate.
