LLC Articles of Organization re-allocation question

[Daniel Bryant]

My partner and I formed an LLC referencing a commercial property that we own together in NY, we used an attorney to draft the LLC partnership together at a 49/51 split. We now are looking to change that to a 50/50 split and I wanted to know if we still need to do that with legal aid or can simply amend that on our own with written/signed consent from each other.
