As previous poster says she needs a good solicitor. Fairest thing would be to get 3 valuations from auctioneers on the value of the house, subtract what she has contributed (savings & mortgage payments), plus the site, (presumable her site alone as gift from her parents to her). Divide what's left into two, probably as you say not much, particularly as it's relatively recent and then when you have this figure pay that if she can afford it. Boyfriend seems to be forgetting he'll have to pay maintenance, maybe what she has to pay him out of the house profits can be used as maintenance. Right now she should get out a diary and record everything she is paying and what he contributes to the child's maintenance and when he has visitations with the child and any threats he makes, might be better if she sees the father as little as possible or only when someone neutral is present. Also she needs to figure out everything she contributed to the house being built. It will be helpful when she goes to a solicitor. This advice is based on one side of the story. At the end of the day it's better for the child if everything could be settled amicable. He will the child's father forever.
