In Ohio (as in other states that have enacted a Domestic Asset Protection Trust Statute), it may be advisable to have two or more trusts as part of an overall asset protection plan.
For example, a husband and wife may each want to have their own, separate Ohio Legacy Trust. Not only can this help to keep certain assets separate, but the respective trusts can then co-own other assets -- like interests in an LLC. In many states, a multi-member LLC provides better protection than a single member LLC.
Keep in mind that this kind of planning -- like all asset protection planning -- requires careful attention to a wide variety of factors, including tax considerations. Many variables often need to be considered before deciding on a particular plan.
In any event, using more than one DAPT (just like using more than one LLC or other business entity) may be advisable in many situations.
