A so-called friend of mine called me up and said her new step-dad's ex-wife was giving him some horses they needed somewhere to keep the horses for a little while, and someone to teach them how to care for and how to ride horses, and asked if they could put their horses on my Dads property and me teach them what they need to know about owning horses. Said they were getting three horses (2 older dead broke geldings and a young mare) and giving me the little mare as pasture rent and because she was wild and crazy and not broke. When the horses arrived they were super skinny and malnourished. I took on responsibility of her feed bill, her hoof bill, her worming, and now her vet bill. We've had these horses for approximately two and a half months and in this time this little mare, approximately 3-5 years old, has fattened up pretty well, I've had her on 14% sweet and all the pasture grass she could ever want. She's been wormed twice, ivermectin and Safeguard. I made the comment around these people that she's gotten so far she almost looks like she's pregnant. They have moved their horses to their own back yards, and are now harrassing me saying if my mare they gave me is pregnant then the foal is theirs because they gave me the mare. Both of their horses are geldings, and if she is pregnant we have no idea who the sire is. Never once did they say anything about her being pregnant or even looking like she could be pregnant until I spoke up about it first. And she's got it stuck in her head that I told her the foal was gonna be hers, never once did I make that agreement and there is no paperwork saying they gave me the horse but I have both of my farriers, my property owner, and soon my vet to vouch that she GAVE me the mare. She plainly stated she doesn't want the mare she wants the foal. So, with all that vented... What are the legalities to this? Does she have any rights to the foal, if my mare is pregnant? First two pictures are from three days ago, second two pictures were taken July 27th which was about two weeks after their arrival.
