I am a single parent to an adult son and three younger children. My adult son is in his early twenties and has been working in a permanent, full-time job for the last two years. He previously lived at home full-time, but from July of last year he gradually started dividing his time between home and his girlfriend's house, quite often staying overnight there. He continued with this arrangement until around October last year and then between October and January (about 3 weeks ago) he spent all of his time round at his girlfriend's house. He still kept many of his belongings in his bedroom in our family home though. About three weeks ago, he then decided he wanted more space from his girlfriend and he is now dividing his time between the family home and his girlfriend's house again.
I am in a pretty precarious financial situation right now. I previously had a very successful business, but I have had to put my career on the back burner for the last decade or so to care for my younger two sons who have additional educational needs.
Up until the end of October last year, my son paid me £150 per month towards bills. However, at the end of November, I told him that he could reduce the amount he paid me to £75 per month as he had spent so much time over at his girlfriend's house. Now that he is dividing his time between the family home and his girlfriend's house with no fixed schedule, I am not sure how much I should charge him. I lost my single person's 25 % council tax discount when my adult son left full-time education and I am still paying 100 % council tax now that he is living here part-time. The difference between 75 % council tax and 100 % council tax is almost £60 per month. Any suggestions regarding how much I should expect him to contribute would be welcome. Thank you.
