Yes, a life insurance policy can become part of an estate under certain circumstances. When a policyholder passes away, the proceeds of the life insurance policy are typically paid to the designated beneficiaries. However, if the policyholder did not name a specific beneficiary or if the named beneficiary is deceased, the proceeds may become part of the policyholder's estate. This can happen if the policyholder's estate becomes the default beneficiary due to the absence of a living designated beneficiary. Additionally, if the policyholder has assigned the policy to someone else or if the policy is owned by the insured's estate, the proceeds may also become part of the estate. It's important to note that the specific laws regarding life insurance and estates can vary by jurisdiction, so it's advisable to consult with a legal or financial professional for personalized guidance in estate planning and life insurance matters.
