This was back in the 1990s (you know last century so nothing may be applicable today as that was back in those days you had to actually steer a car to drive it somewhere)
Before we ever had a horse on the place we incorporated the Farm. The farm was setup a C Corp. in order to allow it to freely give scholarships The Farm had its board of directors who negotiated a lease from the land owners (us). Farm had its insurance with a commercial provider (the same agent we used for the other businesses).
Homestead was insured with Nationwide who never said anything nor questioned anything other than “oh you have German Shepherd Dog?” Yes. Well that is another $1,000 per year for That Dog. (but he was worth every penny as no one set foot on the place that he did not approve)
Otherwise there was never a question. Daughter as a employee of the Farm even ran a summer riding camp for about six years The farm had its board meetings when we were attending regional or national shows so the farm picked up most of the travel expenses
We had a very diligent CPA who knew farm/ranch tax laws and an attorney who understood corporation structure. Our insurance providers were recommended/approved by our advisers
Farm made money, paid its taxes and was dissolved when I closed my other businesses upon being hired by a national corporation as the Farm lost its primary client.
My primary business (was set up as a S Corp) owned the horses which then boarded the horses at The Farm. The S Corp was actually using the horses for advertising the business and to gain access to parties who could use its services similar to others using a country club golf course to meet clients.
When I was hired buy a manufacturer the S Corp sold the horses to us which we gave to the kids and it appeared nothing ever moved as everything appeared just as it once was… all the transactions were just the shuffling paper from one side of the table to the other.
Why did we do this? I wanted firewalls between the businesses and our personal assets. This structuring provided very clear lines that could be easily defined as this belong to that and that was to this.
The business activities had their own potential dangers as they were working on high profile projects that all had inerrant risks that I did not want to extend into my personal life.
In the military I had been a combat air traffic controller (both tower and radar control ratings) so was used to doing multiple tasks, keeping multiple items separated but on tracks to keep the aircraft safe (the field I was at had thirteen approach departure routes with a take off or landing about every ten seconds during daylight (about 3500 per day). There never was an incident at this field
