Long story short, it looks as though DSS (nearly 8) will be coming to live with us (his dad, me and his half sister, 4). He has been having trouble at school and his step father (married to his mum) gave his mum an ultimatum to choose between him or her son. She appears to have chosen her husband. They (DSS's mum and stepfather) have another 4 children together and DSS's sister who is 13. Neither of them work.
My partner and I both work long hours in professional jobs (7-7) so will need extra childcare (DD is in nursery full time). My partner is often away with work abroad.
We currently live about 25 miles away, so DSS will need to change schools.
My main concerns are to get something legal in place as the last thing I want is for DSS's mum to change her mind two months down the line (she is not the most stable of people - she is also pregnant again). What do we need here? A residency order? Can this be fairly simple and non-contested? Can I apply for parental responsibility? I do not want to be in a situation if his dad is away with work, he needs medical attention and I need to try and contact his mum and am unable to make decisions on my own. His mum has always refused to speak to me despite her ending the marriage with my partner before I knew him. Me and his dad are not married in case this makes any difference.
In terms of finance this will be very difficult for us - I understand (however strange it seems to me) that because his mum doesn't work we will still have to pay maintenance for DSD? We will get nothing back from ex-wife. We will also have to find childcare for wrap around school hours 7-7. We do not quality for any tax credits. I estimate we're looking at least another £400pcm for childcare and school holiday care. Plus the maintenance for DSD ongoing.
Another option would be for my partner to give up his job. He does not want to do this, but the extra costs may not be possible for us otherwise. I presume his ex wife could not claim maintenance from me?
We will contact a solicitor about this as soon as we can - difficult because we're both at work and 80 miles away during the day. DSS had to be picked up last night and is staying temporarily with his grandparents as his mother and stepfather wanted him out of the house.
Does anyone have any advice? I know it's long! We just want whats best for DSS. Am I right to insist on some sort of legal agreement before going into this?
