The firm

A steady hand across contentious and advisory matters.

S.O. Onubi & Co. is a dispute resolution, transaction advisory, and notarial practice built on a simple premise: sound judgement, delivered plainly, is what clients need most.

Judgement

The right answer depends on the facts and the stakes. We weigh both before we advise, and we tell clients what is in their best interest in the circumstance.

Discretion

Sensitive matters are handled with utmost confidentiality and discretion. The information that clients share with us stays with us.

Diligence

Cases are won on diligent preparation. We do the detailed work — on the evidence, the law, and the strategy — that outcomes turn on.

Clarity

Law is complicated; advice should not be, and with us, it is not. We explain the position of the law, apply them to the facts presented, explore the available options, and the costs in lucid terms that clients can act on.
