My question relates to legal practice in the state of: Massachusetts

I read online that the statute of limitations on filing a legal malpractice case is three years, but Iím confused about when the date begins. A sibling and I hired a lawyer over ten years ago to set up a Trust, and the sibling started taking legal action against me in 2015 with this same lawyer over an issue involving the same Trust. The legal action began as a threat, and I wasnít sued until last year, although with a new attorney. Iím considering suing over what feels like a blatant conflict of interest violation. Would the clock start ticking as soon as I was first contacted, or when I was first sued, although again, with a new attorney who took over the case.

Thanks for any information.
