Still, relatively few Americans have long-term care insurance, partly because the premiums can be hefty, especially for those with poor health histories. Many people simply underestimate the cost of long-term care or would rather not think about maybe needing it someday.
Medicare typically provides limited long-term care coverage, and to qualify for Medicaid, it may be necessary to spend down your assets, said Carter. In some states adult children may be on the hook for their parents' long-term care bills.
Nationally, the median monthly cost for an in-home health aid (for 44 hours a week) is $3,861, according to a study by insurer Genworth Financial. For a private room in a nursing home, the median monthly cost is $7,698.

For those who want to pass on wealth to the next generation, trusts can be a useful tool for doing so, experts say.

Trusts can also keep your estate out of probate court — which can be an expensive and time-consuming process — and minimize estate taxes.
Most estates aren't subject to federal estate tax, since the current exemption for individuals is $5.45 million and $10.9 million for married couples. But many states have much lower estate-tax thresholds, Carter noted.
Expenses tied to the probate-court process can also chip away at your estate, leaving less for heirs, he noted. That's one reason to consider establishing a living trust, in which assets are held for your benefit during your lifetime and transferred to your designated beneficiaries after you die.
