Symons Vs. Heaton Gary Plachek and Curtis Symons met in 1964 in 7th grade. They remained close friends until Placheks death 46 years later. In 2001, Placheks elderly mother expressed concern to Symons about her sons excessive drinking. She asked Symons to take care of her son after she died. Symons was a recovered alcoholic, whereas Plachek was an alcoholic with no desire to stop drinking. In mid-2001, Symons moved into Placheks home at Placheks request. Symon lived there until Placheks death in 2010. Symons did not pay rent. He continued working at his job but also cared for Plachek by driving him places, running his errands, taking care of his dog, maintaining the household, and doing other tasks as needed. Plachek, who was unemployed, spent much of his time drinking alcohol and sleeping. After Placheks death, Symons filed a creditors claim against Placheks estate in the amount of $259,200. In this claim, Symons sought compensation for the care and services he provided to Plachek. The estates co-administrators, Wayne Heaton and Timothy Tarver, denied the claim. Symons then sued Placheks estate, asserting claims for implied contract, promissory estoppel, and unjust enrichment.
