     One of the trainers at the barn I board my horse at found someone to half lease my horse. I work full time and I also do online college so I only have time to ride 3-4 days a week. I have boarded my horses at this barn on and off for the last 10 years and I know the owner well. I have worked for her in the past as well. 
     The trainer let me know a few days ago that she found someone who would work well with my horse. This was amazing news because I had a lot of criteria in order for someone to lease him and the potential leaser seems perfect! I have been working hard over the past week in order to get him ready for the test ride and have been out to the barn every day. 
     The test ride was supposed to be tomorrow and the trainer told the barn owner about it. The barn owner said no “this lady has plenty of other horses to ride here”. The barn owner has over 80 horses and is maybe having trouble finding work for all of them. I mean no disrespect to the barn owner but she owns mostly western trained horses, ponies, and mustangs. My horse is a 18 hand ex fox hunting horse who is a complete joy to ride. The potential leaser wants a large horse since she is tall, wants to do some fences, and is most comfortable riding hunter horses since she started at a hunter barn. I think my horse is the right fit for her compared to any of the barn owner’s horses. 
     It even crossed my mind to ask if I could half lease my horse out. There doesn’t seem to be anything barring half leases in my board agreement. I asked a lady who boards and half leases out her horse if she had any trouble. She say the barn owner was upset originally but then gave permission for the half lease once she realized she knew the potential half leaser. The trainer advised me to message the barn owner about this and I have no idea what to say. The barn owner may get angry and I am afraid of being kicked out. I want to explain to the barn owner that I want to save more money in order to pay for my college. I need my horse to have proper care and exercise. I am in no way trying to swindle her. Maybe I can convince her by saying the leaser will have to take lessons per the lease agreement that way she will get some money out of it. 
   This is a tough situation but the next closest barn is 45 minutes farther than my current one so it is not an option for me with my already tight schedule. Thank you if you read this whole thing. I would really appreciate some advice. 

Help! Barn owner will not allow me to half lease out my horse.
