Traditionally the new spouse would receive a life estate ( the ability to live in the home for the rest of their life) and the children of the deceased parent who owned the home would receive the remainder of the property after the death of the surviving spouse or their step parent.
A Florida Estate Planning Lawyer can create documents that change or alter the homestead rights of a surviving spouse. Remember that it may not be your spouse making the decision, but the government or an agent acting under a power of attorney who make the decision and they may not agree with what you and your spouse decided upon years earlier. It is best to create a post nuptial agreement or valid waiver to address these issues while everyone agrees and before it is too late.
Contact a Jacksonville Estate Planning Lawyer or Florida Estate Planning Lawyer to discuss creating documents that address these issues and protect your spouse and children from the influence of others.
