Three years ago, my mother moved in with me and I became her full time caregiver. Last year she changed her will to leave more to me than my sister who hasn't done anything for her care. In fact, she hasn't spoken to mom since she moved in with me. I don't get paid for providing care, but I do use her social security check to help pay for household bills and groceries. Aside from that, mom has a sizeable stock account that she inherited from our dad. I'm worried my sister may cause trouble when mom dies and learns she doesn't get as much as I do. Should I ask her to change her will to be more equal?

I can sense the unease in your voice. As caregiver for your mother, it makes sense that she might favor you in her will, especially if your sister isn’t interested in a relationship with your mom. While your question is more about what happens after your mother dies, my hope is that there will be opportunities to communicate with your sister before that happens, resolve the rift between her and your mother, and avoid the potential conflicts that may arise.  Ultimately the decision to accept the provisions of your mother’s will is hers.

That said, let’s discuss some practical issues to address your concerns, minimize legal complications, and discourage potential disputes with your sister when it comes to your mother’s will.

Understanding the Legal Framework

  • First, it’s important to ensure that the change your mother made to her will is legally sound. The will must have been updated at a time when your mother was fully competent and free from undue influence. Consulting an estate attorney can ensure all legal protocols were followed, thus making it less vulnerable to future challenges.
  • Was the change made with the assistance of an attorney? Although it’s not a requirement, using an attorney to execute legal documents like wills can avoid the mistakes people make when doing it themselves. Often, people will write a will in their own handwriting (called a holographic will). While these may be valid, these types of wills are easily disputed and may not have followed the procedures for valid will executions in the state where the person resides.
  • Assuming your mother did use a lawyer, and at the time did possess the capacity to execute a new will, who was present in the room with your mother’s lawyer when she changed her will? Just your mother? You with your mother? Only you? Ideally, it was only your mother. If you were present, did the lawyer directly address your mother or direct questions to you? The less your involvement in the meeting, the less likely you could be open to accusations of undue influence.

Guarding Against Will Contests

  • If your sister decides to contest the will, she could potentially claim undue influence or argue that your mother lacked the mental capacity to make such a change. To prepare for such scenarios, work with her attorney to maintain thorough records of the discussions and motivations behind the will’s adjustments. This documentation reinforces that the decision was made independently and with full awareness.
  • Did your mother include a no-contest clause to her will? Known as an in terrorem clause, this can discourage your sister from contesting the will, as she risks forfeiting her inheritance if she loses the challenge. While this is not enforceable in every jurisdiction, where applicable, it serves as a strong preventive measure. 
  • A letter of intent can also be included, detailing your mother’s reasoning behind her decisions. This document, although not legally binding, provides context that could be useful in defending the will against disputes. Sometimes, these are prepared by the person creating the will, but the attorney may also provide this service.
  • Keeping detailed records of your caregiving responsibilities and related expenses is crucial. Not only does it validate the more substantial inheritance in compensation for your caregiving role, but it also provides a clear, factual basis for the distribution decision should your sister challenge it.

Proactive Communication and Mediation

Facilitating open communication with your mother and sister could be beneficial. If your mother is comfortable, hosting a family discussion where she shares her reasons for the will’s changes may help your sister understand the context and reduce tension. Transparency often alleviates suspicions and pre-empts conflicts.

If direct communication seems difficult, consider bringing in a professional mediator. A neutral third party can help facilitate productive discussions and address any underlying concerns or grievances. This proactive step can prevent more heated disputes down the line.

Engaging a Professional Team

Engaging the right team is critical. Not only can a team of professionals provide advice and counsel, but their presence and involvement demonstrate that you are not acting alone in managing your mom’s affairs. If her lawyer does not specialize in estate planning or elder law, you can look for one near you by visiting the National Academy of Elder Law Attorneys. Other team members might include a geriatric care manager, financial planner, or family counselor.


By addressing these issues now—through open communication, legal safeguards, thorough documentation, and professional advice—you can reduce the likelihood of disputes and honor your mother’s wishes effectively. While it’s a challenging situation, approaching it with preparation and empathy can help maintain family harmony and respect for everyone involved.
