Hello @tenielle,
It’s a pleasure to meet you 
I’m so sorry for what you’re going through right now with the house. It sounds very stressful.
I’m not a lawyer and wouldn’t know enough to try to offer any mundane legal advice, but it sounds like you are already working to have that angle covered. I hope the legal advisers and police can help you and your children. I’m glad you’re pursuing all options available - it’s a smart thing to do! 
In terms of magickal advice, there are plenty of spells you could cast, depending on how you’d like to move forward. Adding to the suggestions that others have kindly already offered, here are some spells that may be of use to you:
- Sugar Jar Spell for a New Home - could be adjusted to claim back a home that was yours previously or to set sights on new housing
- Legal Blessings Spell to Win a Court Case - can assist with dealing with the legal system (such as legal advisors/police) in the name of justice
- Emptiness Reversal - a spell to return something that was lost back to the caster. Can be adjusted to return lost belongings or a lost house back.
- Good Luck Spells - when going through a tough time, increasing good luck can manifest good things in ways we may not have even considered. This allows the universe to send you good luck where you need it most.
Wishing you all the best, Tenielle - blessed be
