Can you buy a three‑month auto policy for your son‑in‑law's car?
Yes, many insurers offer short‑term auto insurance that can be purchased for three months, and you can name yourself as the primary policyholder while adding your son‑in‑law as an additional driver. The policy will cover the vehicle for the agreed period, after which you can renew, switch to a standard twelve‑month policy, or let it lapse.

How short‑term policies differ from standard coverage
Short‑term policies are designed for temporary needs such as seasonal driving, a short‑term lease, or a vehicle that will be used only for a few months. They typically provide the same liability limits required by state law and may include optional collision and comprehensive coverage, but the premium is calculated for the exact term rather than an annual rate.
Eligibility and documentation
Insurers will ask for the same information they require for a regular policy: driver's license numbers, vehicle identification number (VIN), proof of ownership or lease, and driving history for both you and your son‑in‑law. Because the policy is short‑term, some carriers may impose a minimum term of 30 days and a maximum of six months.
Cost considerations
Premiums for a three‑month policy are usually higher on a per‑month basis than an annual policy because administrative costs are spread over a shorter period. However, you avoid paying for unused months if the car will only be driven temporarily. Discounts such as multi‑vehicle, good‑driver, or bundling with other insurance may still apply.
Choosing the right provider
Not all insurers offer three‑month terms, so you may need to compare a few carriers. Look for:
- Availability of short‑term or "temporary" policies
- Ability to add an additional driver without extra paperwork
- Clear cancellation and renewal terms
- Competitive rates for the desired coverage limits
Alternatives to a three‑month policy
If a three‑month term isn't available, consider a six‑month policy and cancel early (subject to possible fees), or use a non‑owner car insurance policy that covers drivers who don't own the vehicle but need liability coverage.
