Guides and Resource Directory
This directory brings together Nellie Supports’ mental capacity assessment guides, organised by decision type. It is designed for solicitors, deputies, attorneys, case managers, families and professionals who need clear guidance on decision-specific capacity under the Mental Capacity Act 2005. Use the sections below to find guides on COP3 assessments, LPA capacity, financial capacity, property decisions, testamentary capacity, litigation capacity, retrospective capacity and court-ready mental capacity reports.
How to use this directory
The guides on this page are grouped into topic clusters so you can quickly move to the area most relevant to your needs. Within each cluster, you will find detailed articles answering common questions, explaining key legal and practical issues, and helping you understand what may be required before taking the next step.
Some guides are written for individuals and families who want straightforward explanations. Others are intended to support solicitors, deputies, case managers, healthcare professionals and other practitioners who need clearer technical guidance around assessments, evidence, reporting and decision-making.
What you will find here
Our resource library is designed to make complex subjects easier to follow. Depending on the topic, guides may explain legal tests, practical steps, evidential requirements, common misunderstandings, warning signs of dispute, or the differences between similar processes and services.
As the library grows, this directory will continue to act as the main access point for all guide clusters across the website, making it easier to explore related topics in a structured way rather than searching for pages individually.
Who these guides are for
This directory is intended for a wide audience. That includes people seeking support for themselves or a relative, professionals involved in legal or care-related decision-making, and referrers who want to better understand the issues before arranging formal input.
Because many situations involve overlapping legal, health, care and evidential questions, the guides are written to be informative without losing sight of real-world use. They are intended to support better understanding, not replace decision-specific professional advice where a formal assessment, report or legal opinion is required.
