So, my elderly father moved in with me last Jan, 2017 because he lived 200 miles away, nearly died from Copd exacerbation and wanted to move back down near us. Most of his siblings in the area he came from had passed away. I suggested he move in with us, he has the lounge, bathroom next door and shares the kitchen with us. Myself and two sons live upstairs. Originally the plan was for him to buy a place nearby but for one, he's too frail to be completely independent and two, he struggled to sell his flat as it was so neglected and it eventually sold at auction. He decided, knowing that he wouldn't be able to afford a place down here anyway, and living with us, that he would give the proceeds of the sale to myself and two younger brothers. So he wrote me a cheque for quite a large sum and I tried to pay it in on Friday but he had put the date as 2017 so they couldn't accept it. Earlier tonight he told me he had written another so I picked it up, brought it upstairs then realised that he had made a slight mistake on my surname (which happens to be the same as his!) and hasn't initialled it. So, I was going to pay it in first thing tomorrow so would it be unreasonable to put his initials next to the mistake? Or hope they will accept it as it is. He doesn't get up until after 10am so I will already have been to town by then. I also don't want to make him feel bad about another unacceptable cheque!
