Liquidity means having cash when it is needed, not just value on paper.
A family can have a house, retirement accounts, and other assets, and still have a cash problem after a death.
That is what liquidity means. It means having money that can be used now, not later, and not only after selling something, borrowing against something, or waiting for an estate to sort itself out.
In plain English, liquidity is breathing room. It gives a family time to think, plan, and adjust without making rushed financial decisions.
