Execution is everything. The executor of your will is “your personal representative after you die.” Make sure the person you choose is willing to fill the role and responsible enough to handle it. If you have children under 18, “try to avoid appointing the same person as executor and guardian.”
Be specific. Exact language prevents family feuds. Don’t use catchall phrases like “my jewelry.” Instead, write “I leave the diamond ring with two sapphires, set in yellow gold, to my daughter Ann.”
Review regularly. Wills should be reviewed “every few years.” Over time, the guardian you chose for your children may cease being “young and energetic enough” to handle the job. Other people named may have moved or divorced. Review your will soon if you yourself have remarried.
