Hi, thanks for your question. Just a bit more information required to fully assist you:
-Is the child yours?
-are there any formal agreements regarding the property and contributions?
-What is the value of the property and outstanding mortgage?
-What are her qualifications and earning potential?
Thank you. What would your proposals be for the child if you separated?
Thank you. Firstly, in relation to the property she has no legal interest in the home. However, as you have a child together if she cannot suitably house herself and the child she can apply to court to remain in the home until the child is a certain age. The court will fully consider both your financial positions and capacity to obtain and maintain alternative property before making such a decision. However, without a court order she has no legal right to remain in the property or change the locks and you can ask her to leave upon reasoanble notice - she can then attend the local authority housing office and apply as homeless, and given she will have a young child with her she will be deemed priority need and they will likely agree they have a duty to assist her with accommodation.
In relation to the child maintenance you provide her, the calculation they provide is the amount that you must pay. Anything above that is voluntary and unenforceable - so if you stop the payments towards a car that is in her name then she cannot enforce the previous arrangement against you.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you
