The STEP Standard Provisions (England and Wales) (2nd Edition) (SSP2) was originally published on 31 October 2011. It is divided into core provisions (standard provisions 1-13) and optional additional provisions (special provisions 14-23) that are not included unless expressly incorporated. It includes detailed guidance. STEP also published a toolkit for will writers and frequently asked questions (FAQs), which are available at STEP: STEP Standard Provisions.
SSP2 or the first edition can still be used, but STEP recommends using SSP3.
All Practical Law Private Client standard documents for wills provide an option to incorporate SSP3 by reference instead of including administrative provisions in the will document (see Wills toolkit: STEP Standard Provisions (England and Wales)).
