What is my ex entitled to ?

So I'm going through divorce now , only just paid court fee ! Just wondering what might happen , my ex earns around £1100 a month net, gets £662 cms from me and we currently split the joint mortgage 50/50 which is £610 each ! I can not afford to pay cms and 50% of mortage,we have roughly £110k equity in the property ,I'm living with my parents and have done since split , we have two children 14&11, would the court likely allow me to sell the house in order to free up money so I can rent my own place ?? And if that is the case , would my ex still be entitled to universal credit and benefits if she gets say £70k equity from the split ? What is likely to happen in this situation as I cannot afford to live while paying mortage which I am not living in, and my ex won't be able to afford rent without benefits, but will have equity in savings ?

If your ex will receive £70k she will lose her UC, however if she will keep it for 6 months aslong as she can prove she is in the process of purchasing a property, if that's not the case then, she will only get her UC back if it dips below 6k
