Hi my partner and I have been together for five years. I have two grown up children he has a young child. During that time every school holiday his child has stayed with us, I collect him (at least an 8 hour return journey) And drop him off, we buy birthday and Christmas presents Etc and clothes when he is with us. Two years ago my partner was diagnosed With brain cancer. After three major brain operations and radiotherapy plus a permanent shunt fitted his ex is now saying she is going to csa for Maintenance. He doesn’t and can’t work and still has some of the brain tumour left which we are waiting to find out if it is growing and how rapidly. her demands came about because his child was staying with us for the summer and 2 and half weeks in, I asked what the plans were for him returning home (I asked what she wanted/needed/ expected as I wanted to be able to make plans to visit my own children and my family). I work hard and do receive a good salary but my partner doesn’t and can’t Work and doesn’t receive benefits. Can she claim from me? We are not married. We don’t see his child go without but are mindful that any monthly allowance wouldn’t necessarily go on his child as when his child visits hardly any clothes Are packed etc yet his mother has all the latest gadgets, clothes and regularly goes out partying and drinking etc. Can she claim from me? And am I being unreasonable?
