Estate Planning Built on Real Experience — Not Just Theory.
TrustFully was founded by an attorney who has been on the other side of the table — as a corporate trustee and estate settlement officer handling estates across the United States. That experience shapes every plan, every document, and every client conversation.
About TrustFully — Missouri Estate Planning & Probate Law
Most estate planning attorneys have drafted hundreds of wills and trusts. Very few have sat on the other side of the table — actually administering those estates when families needed help most, working with the IRS, managing complex assets, and navigating the real-world gaps that generic documents leave behind. Derek Haake has done both. That combination of legal draftsmanship and hands-on settlement experience is what makes TrustFully different — and what makes the plans TrustFully creates actually work when they need to.
TrustFully.law
Derek Haake is an estate planning and estate settlement attorney dedicated to helping Missouri families protect what they have built and navigate what happens when life takes an unexpected turn. His practice focuses on creating thoughtful, legally complete estate plans and guiding families through the often-complex process of settling estates and administering trusts after a death.
Before founding TrustFully, Derek served as an Estate Settlement Officer and corporate trustee with Bank of America, administering and settling estates across the United States. He handled taxable and non-taxable estates, coordinated complex asset transfers, worked directly with the IRS and financial institutions, and managed holdings including real estate, business interests, oil and gas leases, and investment portfolios.
Before entering law, Derek was a technology founder and entrepreneur, building and scaling businesses in fast-moving environments. That background gives him a practical understanding of business planning, ownership succession, and protecting closely-held companies that few estate planning attorneys possess.

The Experience That Makes the Difference
Estate planning attorneys are not all the same. The majority of practitioners focus exclusively on drafting documents — wills, trusts, powers of attorney — without ever having experienced what happens to those documents after the client dies. The gaps, the ambiguities, the coordination failures, and the unfunded trust problems all reveal themselves during administration, not during drafting.
Derek’s years as a corporate fiduciary give TrustFully’s clients something rare: plans drafted by someone who has personally administered estates and seen exactly where generic planning fails families.
As an Estate Settlement Officer and corporate trustee with Bank of America, Derek was responsible for the full administration of estates and trusts from the moment of death through final distribution. This was not a supervisory role — it was hands-on fiduciary work at the institutional level, handling estates of all sizes and complexity across the United States.
In that capacity, Derek:
- Administered both taxable and non-taxable estates, including multi-million dollar estates with complex asset structures
- Coordinated directly with the IRS on estate and income tax matters, including estate tax audits and closing letters
- Managed complex asset classes including real estate portfolios, business interests, oil and gas leases, mineral rights, and investment portfolios
- Worked with financial institutions, brokerage firms, insurance companies, and government agencies to collect and transfer assets
- Supervised distributions to beneficiaries, including minor beneficiaries, special needs beneficiaries, and discretionary trust beneficiaries
- Resolved creditor claims, contested matters, and family disputes in the context of ongoing estate administration
This experience gave Derek a detailed, practical understanding of how estate plans perform under real-world conditions — which documents work, which ones create problems, and what the most common and costly failures look like from the inside.
Since entering private practice, Derek has represented Missouri families and fiduciaries across the full spectrum of estate planning and administration matters — from straightforward young family plans to complex multi-generational trust structures, contested probate proceedings, and business succession planning for closely-held companies.
His private practice experience spans:
- Estate planning — revocable living trusts, wills, powers of attorney, healthcare directives, and beneficiary designation coordination for individuals and families at all asset levels
- Trust administration — guiding successor trustees through the full administration process, from trustee notices through final accounting and distribution
- Probate administration — representing Personal Representatives in Missouri probate courts, from petition through Letters Testamentary, creditor management, and final closing
- Business succession planning — integrating business ownership into estate plans for closely-held LLCs, corporations, and partnerships, including buy-sell agreements, ownership transfer structures, and succession provisions
- Fiduciary representation — advising executors and trustees on their duties, liability exposure, and proper procedure throughout the administration process
Before law school, Derek built and scaled technology businesses — giving him direct experience as a founder, employer, and owner navigating the challenges of growing a company in a fast-moving environment. That background is not incidental to his legal practice. It fundamentally shapes how he approaches estate planning for clients who own businesses.
For many Missouri families, the business is not just an asset — it is the livelihood, the identity, and the intended legacy. An estate plan that treats a closely-held business as just another line item on an asset list will fail those families. Derek approaches business succession planning with a founder’s understanding of what is actually at stake:
- What happens to the business if the owner dies suddenly — who has authority, who can sign, who can access accounts
- How buy-sell agreements interact with estate plans and life insurance to create a workable succession structure
- How LLC membership interests, S-corporation shares, and partnership interests are properly assigned to trusts without triggering unintended consequences
- How to structure ownership transitions for family members or co-owners in a way that is fair, tax-efficient, and legally sound
About TrustFully — Built to Be Different
TrustFully was created with a specific purpose: to combine the depth of Derek’s estate settlement and planning experience with modern technology and a genuinely client-first approach — making high-quality estate planning accessible, efficient, and tailored to real Missouri families without the friction, intimidation, or outdated processes that keep people from getting protected.
Plans that are built to work, not just to look complete. Every TrustFully plan is designed with the administration process in mind — not just the signing ceremony. That means funded trusts, coordinated beneficiary designations, properly executed documents, and clear instructions for the people who will implement the plan when it matters.
Virtual by design, not by necessity. TrustFully operates entirely remotely — not because it’s convenient, but because it’s better for clients. No office overhead means more time focused on the actual work. Missouri’s recognition of electronic wills and remote notarization means legally valid execution without any of the traditional friction.
Transparent pricing. Flat-fee estate planning with no hidden costs, no hourly billing surprises, and financing available for families who want to protect their children now rather than when budget timing is perfect. Probate fees are set by Missouri statute — you know what you’ll pay before you start.
A relationship, not a transaction. Life changes. Families grow, assets are acquired, circumstances shift. TrustFully is available after the plan is signed — for amendments, updates, questions about implementation, and guidance when something unexpected happens.
