The single most common problem that arises following death is unknown accounts or improperly designated assets or accounts. You should document the assets you own, the current ownership structure, and the location of the accounts.
You should let a trusted contact know where your digital accounts are located and what, if any, direction you have for those accounts.
You might provide disproportionate transfers between children during lifetime. Use this spreadsheet to give direction on whether such disproportionate gifts should be taken into account following death.
Your family may not have a clear understanding of what charitable gifts you currently make, and what charitable gifts you might like them to make following your death.
You should identify any unique assets you own. You should identify what value exists with the unique assets, and why an asset may have sentimental value to you.
You should give specific directions on your end of life care, identifying the impact that your decisions will have on your community.
