Ownership options

There is nothing quite like the thrill of racehorse ownership and trainer William Knight seeks to make it as memorable as possible.

William and his wife Emily offer a really warm welcome to owners at Rathmoy Stables. Along with the team at the yard, the Knights aim to always go the extra mile, so that owners can derive maximum enjoyment from their investment.

William also encourages joint ownership and racing partnerships - options which allow a group to spread the costs as well as really get a buzz from a shared venture. Indeed, there are other possibilities -such as company ownership and leasing. Please see the possible owner options available and do contact William and see if there is an ownership opportunity that works for you.

Rathmoy Stables is open to the general public on an appointment / pre-arranged basis and also hosts for Newmarket Tours.

Sole Ownership

You will be the owner of the horse and no one else. As such, any costs and profits will be yours alone. You will also have a close involvement with any of the decisions regarding the horse. You will be able to choose the name of your horse and which colours will be worn in your name.


Co-ownership of a racehorse involves the participation of more than one owner. It is effectively any type of racehorse ownership other than sole ownership. Entering into co-ownership of a racehorse can lead to a number of different variations in how you the owner are involved.

Types of Co-ownership

There are 4 types of co-ownership:

Company Ownership

The horse is owned by the company’s shareholders.

The company must appoint a Registered Agent to act on its behalf.

Joint ownership

Can consist of between 2 and 12 individuals.

The horse(s) can run in either a joint ownership’s name or the name of a joint owner.


Leasing a racehorse involves ownership of a racehorse for a set period of time, perhaps for one race or for its racing career

Costs that the horse incurs become the responsibility of the lessee for the lease period and in return the horse will run under the ownership of the lessee

At the end of the lease the ownership of the horse returns to the lessor/the legal owner

It is important that an agreement is made between the lessor and lessee with regard to the lease period, prize money split, if any, and any exceptional costs that may remain the lessor’s during the period

The ‘Free Lease Exchange’ is another option for owners to consider. The scheme is restricted to members of the TBA & ROA with British consigned/owned horses. It is a joint initiative by the ROA and the TBA to put breeders of available horses in contact with prospective owners, by allowing breeders and vendors to offer their horses on a free lease.

Racing Partnership

Can consist of between 2 and 20 individuals of which at least 2 must become, or already be, registered owners.

There are a number of ways in which partnerships are set up and managed. You must decide upon how much input you would like as a co-owner and then choose the type of co-ownership to suit you. The 3 types of partnership are as follows:

Trainer managed

This involves a trainer setting up and running a co-ownership. The trainer will usually become a co-owner themselves. This means all the admin of running the co-ownership is carried out by the trainer thus providing ‘hassle free’ racehorse ownership. We currently run Angmering Park Thoroughbreds and will be setting up future syndicates in the future. Please contact the office should you be interested in joining one of our syndicates.

Social group

This involves a group of friends deciding to start up a co-ownership and share the costs accordingly. One co-owner or more will have to set up and run the co-ownership and deal with the administration of the co-ownership.

Professionally run co-ownership

There are a number of professional co-ownership organisers who work on a commercial basis and charge a management fee to set up and run co-ownerships. This means all the admin of running the co-ownership is carried out by the co-ownership organiser thus providing ‘hassle free’ racehorse ownership.

Racing Clubs

Racing Clubs are not an independent form of co-ownership. Therefore by joining or becoming a member of a Racing Club you receive the benefits of that Club but are not entering into racehorse ownership yourself.

Will involve the ‘leasing of an ownership interest’, but does not involve ownership of any racehorses. The Club itself may own any number of horses, which will run under the colours of the Racing Club.

Involves registering as a member of a club by paying a joining fee and/or a membership fee for a specific period. Re-registration will normally be necessary after this period.

There may be some ownership benefits including a share of prize money. A Racing Club should not be just the use of a premium rate tipping service.
