Equine Law Industry Group

Ms. Mayer, the Co-Chair of the Equine Law Industry Group, advises clients in all aspects of the equestrian industry. Ms. Mayer has curated a team of attorneys at the firm who can handle all the needs of those in the equine industry. These highly skilled attorneys have extensive experience in their given field of expertise and can assist clients from A to Z in the equine industry including business formation, contract drafting, taxation considerations, estate planning, labor and employment, real estate, government law and policy, intellectual property and branding, and even through litigation.

Ms. Mayer’s interest in equine law grew out of a frustrating experience buying a horse. Realizing she would have to draft her own bill of sale, she got to work researching all that goes into a bill of sale, the potential pitfalls, and the potential liabilities that can stem from a poorly drafted contract. This experience really opened her eyes to the large need for lawyers in the equine industry.

The longer Ms. Mayer is involved in equine industry, the more she recognized the need for experienced lawyers that understand the equine industry. After wanting to start an equine legal group at the firm for quite some time, it was not until three other attorneys with extensive equine experience joined Buchalter in the Spring of 2022, that the group became a reality.

Ms. Mayer has advised clients on the purchase, lease, and sale of horses. She has also advised clients on long term horse property leases. Ms. Mayer, with her extensive litigation background, takes her intimate understanding of what can go wrong with contracts related to horses and advises her clients on the best ways to avoid any confusion, misunderstanding, or even litigation. Ms. Mayer’s personal experience buying and selling horses also informs her in her equine law practice. Being involved in the equine industry is invaluable to her clients.

Ms. Mayer is currently on the hunt for a new equine partner in Europe and hopes to do the high amateur owner classes one day with this yet to be discovered unicorn.

Ms. Mayer looks forward to helping everyone in the equine industry to protect their hard work and assets. Lawyers should be involved in horse related deals but these lawyers need to have a personal understanding of the equine industry, the nuances of working with horses, and the special needs of equine related businesses.
