What are these lines?

And I would add getting copies of the water bills. These would show if extreme amounts of water were consumed - which is what happened in my case! Had we asked for copies of water bills, we would have noted summer months with beyond excessive water usage, for a home with two adults. They were basically refilling the pool, instead of repairing the pool (i'm talking one month 96,000 gallons of water). And during the months they no longer lived in the house - thousands and thousands of gallons of water (for an empty house!).

Lucky for you, those records can be attained through the court system without too much hassle. But I am sure your lawyer already knows this.

My dear wife was in R/E sales for a number of years and pushed her buyers to get a history of the utility costs/bills. Of course, in a seller's market...they could simply tell the buyers to go pound sand.

Probably the spa can be saved if some sort of extra support is added to stop it from leaning - but I don't even want to imagine what that would cost!

I don’t know if a structural engineer would help or not. I am wondering if some helical piers under the bond beam is a thing that would work with pools like this.

Structural Engineer expert in swimming pools needs to be involved.

Thanks for the additional pics, and I'm sorry you're having to go through this nightmare! The crack in the bottom of the pool would not be freeze related, assuming there was water in the pool. I would definitely want to do a full chip out and see if the crack is in the shell itself. The skimmers and other leaks could potentially be freeze related, depending on depth and if they were holding water. Judging from your picture, the decking is absolutely sinking. However, the decking is only loosely connected to the bond beam with mortar. The bond beam should be tied into both the entire pool wall and hot tub with rebar. Are you certain it is also pulling away and sinking? Are you seeing any cracking in the bond beam wall or the hot tub? It's hard to tell in the pic, and the only way to know for sure is to get the decking out and dig down to verify. You'd need to do this to get proper compaction and/or do helical piers if necessary prior to fixing the sinking deck. If the shell and bond beam are in good shape, it could save you a lot of money.

Thank you! Here are some more images of this 'pulling away' where the pool and spa are connected. I also did like a sketch of what is happening. I am wanting a structural engineer to verify exactly what the issue is.
