Specific actions can increase the risk of estate disputes among loved ones.
You have likely heard the advice to "get it in writing" to protect your interests and to serve as evidence should someone challenge the arrangement in the future.
This concern is one reason why properly drafted and signed estate planning documents are essential to transferring wealth.
When it comes to estate planning, bequests and promises do not exist unless written into the legal instruments.
Failing to understand or adhere to this reality can lead to significant legal disputes among heirs.

Comprehensive estate planning with an experienced attorney can reduce the risk of family estate disputes.
Verbal communication of your intentions to your children is insufficient to carry them out.
A court must act according to what is in your last will and testament, trust, and beneficiary designations.
Absent your clear, written intent, your instructions do not exist.
Consequently, when your verbal wishes are not also written in your estate planning documents, heirs can feel betrayed.
Confusion and conflict can also arise through changes made to estate plans later in life.
While a parent may legally be able to make gifts of assets to a child without consulting the rest of the family, this can lead to resentment among the other family members.
Disputes among siblings are often present under certain circumstances.
What are these?
Unequal distribution of assets.
When one child receives a larger inheritance than his or her siblings, rivalries can arise.
If no reasons for the unequal inheritances, a court battle may ensue.
Unclear estate documents.
When a last will is ambiguous or outdated, your family can dispute its interpretation.
Blended families.
When parents have children from multiple relationships or marriages, expectations and situations can be complex.
Caregiver favoritism.
When a child who serves as the primary caregiver for parents receives a larger share of the estate, other children may accuse the caregiver of exerting undue influence.
Working with an experienced estate planning attorney can help you address these factors to reduce the risk of estate disputes.
Court battles can both divide families and reduce the value of the estate.
Courts do not uphold verbal statements regarding asset distribution.
They require signed estate planning documents.
In these instances, mere words have no legal authority.
Even a last will and testament does not have the final say on assets with beneficiary designations.
For example, the beneficiaries designated on life insurance policies and retirement accounts will override any instruction in a last will.
Only legally recognized documents carry weight in estate planning.
Even if a mother tells her two children she plans to divide her estate equally, the children may receive different inheritances if her estate planning documents are not carefully coordinated with the beneficiary designations on her assets passing directly to her children.
Although the child with a smaller inheritance may be upset and see the situation as unfair, they will have little to no legal recourse.
Parents can take specific steps to reduce the risk of estate disputes.
Document Intentions Clearly
Vague estate plans are not helpful.
They can lead to conflict over interpretations.
People should clearly outline their wishes in their last wills and trusts and regularly review and update their documents after life events such as births, marriages, or significant asset acquisitions.
Communicate With Family
Although verbal promises are not legally binding, parents should share their wishes outlined in their estate planning documents.
They should explain the rationale for their choices
This transparency is especially true if children will receive different inheritances.
Use Legal Safeguards
Experienced estate planning attorneys can create a comprehensive plan to protect against estate disputes.
By including “no-contest” clauses in the estate plan documents, families can dissuade family members from challenging the estate plan.
If parents record the reasons for their choices in writing, they underscore the validity of their decisions.
Many families struggle to navigate personal expectations and legal realities.
An experienced estate planning attorney can create legally valid and enforceable documents, address potential conflicts, and provide guidance on equalizing distributions.
If your family is at risk of estate disputes, work with an experienced estate planning attorney to create a plan to meet your needs and guide you through communicating your wishes to your loved ones.
Courts require written and legally valid documents to guide asset distribution rather than verbal promises or hearsay.
Although often warranted, unequal distributions can trigger family conflict and rivalry.
Communicating your wishes outlined in your estate planning documents and providing the reasoning for your decisions can reduce the likelihood of misunderstanding.
An experienced estate planning attorney is key to helping you create an estate plan to protect everyone you love and everything you have.
