interpretation of will

[sigma]

I came across an ancestors will from 1841. Can somebody please interpret the following extract.

"And I expressly declare that it is my desire that my said son Edward shall notwithstanding he may have had any conveyance made to him of any part of my said real estate receive only his due proportion with the rest of my said children and in case of his agreeing to do so then that any security I may be in possession of at the time of my decease from my said son Edward shall be null and void."

[Count-A-Strong]

Sounds like he thought that Edward may try to contest his share of the will and this was a clause to protect his wishes should this occur.

[squarebear]

Yes, if Edward tries to get more than his share, he gets nothing.

[dotty.]

Edward must have taken out a mortgage with his Father when he started his own business but that on the fathers demise, the will provides for the mortgage to be void and the land mortgaged would become part of the estate of the father and thus all divided equally amongst the children.
