Questions
What estate planning documents do I need?
Essential documents include wills, revocable living trusts, durable powers of attorney, and healthcare directives. We customize these tools to meet your specific needs while minimizing tax exposure and probate requirements.
How long does probate take in Massachusetts?
Simple estates typically take 6-12 months, while contested cases may require 1-3 years. We streamline the process through efficient court filings and proactive resolution of creditor claims and tax issues.
Can you help with out-of-state property?
Yes, we handle multi-state estate and real estate matters, including coordinating ancillary probate proceedings and structuring ownership to simplify cross-jurisdictional asset management and transfer.
What's the difference between a will and a trust?
Wills require probate court validation, while trusts allow private asset distribution without court involvement. Trusts also enable lifetime asset management and can provide tax advantages for larger estates.
Do you offer initial consultations?
Yes, we provide comprehensive initial consultations to assess your legal needs and develop tailored strategies. This includes reviewing existing documents and identifying potential estate planning or business law concerns.
