Getting the right property and casualty insurance coverage may not rank high on your list of financial priorities. Compared with investment decisions and estate planning issues, questions about the language in your homeowners policy, say, may seem hardly worth considering. Yet the more successful you become, the more complicated your asset-protection needs are likely to beand the more you have to lose. Suppose, for example, that in addition to your primary residencea historic homeyou also own a house at the beach and a condo in the city. The properties are in three different states. The value of your collection of Abstract Expressionist paintings has grown rapidly. And you just volunteered to serve on the board of directors of a charitable organization.

Almost every aspect of this situation could cost you dearly. Insurance laws may vary widely from state to state, different kinds of property require specialized coverage, and collections of art, antique cars, and other unique items may be difficult to protect fully. Meanwhile, serving on a nonprofit’s board could subject you to additional personal liability.

Safeguarding yourself and your family may mean buying additional coverage, but more insurance isnt necessarily the solution. Rather, its important to review all of your needs, consider specialized policies or policy options, and coordinate your coverage with other aspects of your financial situation. Here are 6 different shortcomings that could prove costly.

1. Leaving gaps in homeowners coverage. Any homeowner needs to review coverage regularly to keep up with rising replacement costs. But insuring different kinds of homes in different locales poses extra challenges. If you buy insurance from more than one carrier, you may face contrasting rules, limitations, and policy renewal dates. For example, the liability limit on the policy for a second home might fall below the minimum on an excess liability policy designed to complement the insurance on your primary home. You could wind up responsible for the difference.

2. Ignoring properties unique characteristics. One perk of affluence is the means to own exceptional homes; one drawback is that they may be difficult to insure adequately. Standard homeowners coverage wont pay for the materials and craftsmanship needed to rebuild that 19th century showplace youve painstakingly restored. Coastal homes may face hurricane damage, while a place in the California mountains could be subject to earthquakes or wildfires. Meanwhile, city co-ops or condos may need policies tailored to their buildings or associations coverage.

3. Under insuring art and collectibles. Standard homeowners policies limit coverage for the losses of antiques, furs, and other valuables. And while you could schedule additional coverage, insuring the real value of a collection of contemporary art or vintage muscle cars likely will require a specialized policy addressing several critical issues. How is the value of the collection determined? (Youll need a professional appraisal when the policy is designed, with frequent updates as items appreciate.) Will a damaged or destroyed item be paid for with cash, or will you be required to have it replaced or restored? Will additions to your collection automatically be covered?

4. Forgetting to insure household employees. When someone works for you or your family, as a nanny, landscaper, personal assistant, or in another role, you could be liable for medical expenses and lost wages if the worker is hurt on the job. Several states require household employers to pay into a workers compensation fund, while in other states its optional, but providing such insurance may be mandatory for ensuring your financial well being. If an employee drives your car, also make sure he or she is included on your policy.

5. Neglecting your liability as a board member. Excess liability coverage could help protect you if youre sued as a director of a nonprofit’s board. Or for more comprehensive protection, you may want to consider special directors and officers liability insurance.

6. Failing to get frequent policy reviews and updates. Your financial life isnt static, and neither are your insurance needs. The value of a collection may increase; extensive home renovations could mean a sharp rise in the value of your property; and the re titling of assets as part of your estate planor because of divorce, a death in the family, or the birth of a childcould necessitate policy changes. Even lacking major events, you probably need a comprehensive review of all your insurance coverage at least every two years.
