How can My wife and I leave all our properties, including houses and savings to my only one daughter?

You can leave all of your assets to your daughter in your will.  If you and your wife both do wills, one will have a survival presumption meaning there will be a clause in one will that says "if my spouse and I die together, its going to be presumed that I survived".  The other will says "Its is to be presumed that I died first".  This way, one estate pours into the other, and then the second will is what governs the distribution.  If your daughter keeps all of her inheritence separate and does not co-minlge the money with marital assets, the inhreitance does not become part of equitable distribution and will not go to her husband.
