Many older adults rely on family members - often spouses or adult children - to provide care as they age. However, a recent study found that nearly one quarter of older adults in the U.S. can be considered elder orphans or solo agers.

If you are single and do not have children or other family you can depend on to watch out for your well-being, here are some steps you can take to plan for care in your later years.

Essential Documents
If you haven't already done so, your first step is to prepare a basic estate plan of at least four essential legal documents. This will protect yourself and make sure you're wishes are carried out if you become seriously ill or when you die.

These essential documents include: a "durable power of attorney" that allows you to designate someone to handle your financial matters if you become incapacitated; an "advanced health care directive" that includes a "living will" that tells your doctor what kind of care you want to receive if you become incapacitated, and a "health care power of attorney," which names a person you authorize to make medical decisions on your behalf if you're unable to; and a "will" that spells out how you'd like your property and assets distributed after you die. It also requires you to designate an "executor" to ensure your wishes are carried out.

To prepare these documents your best option is to hire an attorney, which can cost anywhere between $500 and $2,000. Or, if you are interested in a do-it-yourself plan, Quicken WillMaker & Trust 2022 ($129, Nolo.com) and LegalZoom.com ($179) are some top options.

Choosing Decision Makers & Helpers
Most people think first of naming a family member as their power of attorney for finances and health care, or executor of their will. If, however, you don't have someone to fill those roles, you may want to ask a trusted friend or associate but be sure to choose someone that's organized and younger than you who will likely be around after you're gone.

Also be aware that if your choice of power of attorney or executor lives in another state, you'll need to check your state's law to see if it imposes any special requirements.

If, however, you don't have a friend or relative you feel comfortable with, you'll need to hire someone who has experience with such matters.

To find a qualified power of attorney or executor for your will, contact your bank, a local trust company or an estate planning attorney. If you need help locating a pro, the National Academy of Elder Law Attorneys ( NAELA.org) is a good resource that provides online directory to help you find someone in your area.

Another resource that can help you manage and oversee your health and long-term care needs as they arise, and even act as your health care power of attorney, is an aging life care manager. These are trained professionals in the area of geriatric care who often have backgrounds in nursing or social work. To search for an expert near you, visit AgingLifeCare.org.

Or, if you need help with bill paying and other financial/insurance/tax chores there are professional daily money managers (see SilverBills.com or AADMM.com) that can help.

Aging life care managers typically charge between $75 and $200 per hour, while hourly rates for daily money managers range between $75 and $150.

It's also important to note that if you don't complete the aforementioned legal documents and you become incapacitated, a court judge may appoint a guardian to make decisions on your behalf. That means the care you receive may be totally different from what you would have chosen for yourself.
