Thanks for your question. He has no claim unless he has contributed to the family over the years. The reason for that is that an unmarried partner only has 2 remedies under Scots law. One is for unjust enrichment where he has contributed and it would be unfair for you to benefit from his contribution. The second is a statutory claim for recompense for contributions in your interests or that of any child. From your narrative you have a partner who has contributed nothing and therefore would be due nothing. I hope that helps. Please leave a positive rating so that I am credited for my time.
