Rule against perpetuities meaning

What does Rule against perpetuities mean?
A time‑limit rule used in trusts, wills and land transactions to stop property being tied up for too long. In practice, any contingent gift, class gift, power of appointment or option over land must vest, if at all, within a permitted perpetuity period or it risks being void (often subject to statutory “wait and see” and other saving provisions). In England and Wales, the rule is now largely statutory (Perpetuities and Accumulations Acts 1964 and 2009). For instruments taking effect on or after 6 April 2010, a single fixed perpetuity period of 125 years generally applies, alongside modern wait‑and‑see and class‑closing rules. The rule is disapplied or modified for certain dispositions (for example, some pension and employee benefit schemes, and exclusively charitable dispositions). In Northern Ireland, the common law rule applies as modified by the Perpetuities and Accumulations Act (Northern Ireland) 1966, including wait‑and‑see; there is no equivalent 2009 Act fixed 125‑year default. Scots law does not adopt the common‑law rule against perpetuities. Instead, duration limits are imposed by specific statutes (for example, a 20‑year cap on options and rights of pre‑emption over land), with other controls on long‑term arrangements. In Ireland, the rule is statutory, principally reformed by the Land and...

Overage for property sellers: negotiating and drafting checklist on planning, disposal and development triggers, valuation mechanics, security, part disposals, successors and VAT

Basic terms At the outset, assess whether overage suits the transaction. Your client might be better protected by agreeing a higher purchase price or by entering into a conditional contract instead. Overage provisions can be intricate and expensive to negotiate. If overage is to be applied, consider when the seller expects or hopes to receive a further payment and how the buyer could avoid activating the overage. Ensure the overage includes clear definitions of: the overage period (note that, from 6 April 2010, the rule against perpetuities does not apply to most commercial interests and, if no overage period is specified, there is a risk the arrangement could be perpetual) the property that will be subject to the overage any individual units to be sold or constructed, making clear whether parking spaces and other ancillary areas form part of a unit for the overage calculation Include a ‘good faith’ clause, as this may help if the buyer does something unexpected to...

Overage in property transactions: buyer’s checklist on triggers, valuation, security, releases and tax (England and Wales)

Basic terms At the outset, assess whether an overage arrangement is right for the deal. Your client might be better served by agreeing a higher purchase price or entering into a conditional contract instead. Overage provisions can be intricate and costly to negotiate. If overage will apply, check that the terms reflect the buyer’s intended use of the site. the overage period (note that, from 6 April 2010, the rule against perpetuities does not apply to most commercial interests and, if no period is specified, there is a risk the agreement could be perpetual) the property that will be subject to the overage any individual units to be sold or built, making clear whether parking spaces and other ancillary areas are included within a unit for the overage calculation Include a ‘good faith’ clause, as this may help in the event of a dispute...

Acting for the seller in land option agreements: call/put, option periods, encumbrances, exercise, pricing, tranches and split reversions, VAT and HM Land Registry (England and Wales)

Call or put option? In a call option, the purchaser holds the reins, as it may demand transfer of the asset. The seller should recognise that its intentions for the site could be curtailed by that right, and plans for the property restricted. A put option, by contrast, places control with the seller, enabling it to require the purchaser to take the property and complete the acquisition, obliging the buyer to buy. Option period For a call option, the vendor should be mindful that the land could be effectively frozen throughout the option window, potentially sterilising its use. Accordingly, the deal ought to state a clear long‑stop date to cap the period. The Perpetuities and Accumulations Act 2009 (PAA 2009) removed the rule against perpetuities for options, so those granted on or after 6 April 2010 do not need a specified long‑stop date in this context. Before PAA 2009, a call option lapsed if not exercised within 21 years. Where exercise depends on the buyer securing...

PRACTICE NOTES
Contractual options to renew leases: drafting, conditions precedent, time limits, perpetuities, SDLT/LTT, LTA 1954 and registration (England and Wales)

A contractual option to take a lease for a further term is a ‘call’ option It gives the tenant a one-sided entitlement to demand a renewal lease. The tenant is not compelled to use it, yet upon exercise the landlord must honour the bargain. The ability to seek a renewal lease is commonly conditional on satisfaction of conditions precedent (for example, all rent paid and other tenant covenants observed) – for further discussion see Conditions precedent below. A call option is a contract for the sale of an interest in land within the Law of Property (Miscellaneous Provisions) Act 1989, s 2(1). The option must: be in writing contain or incorporate all of the terms expressly agreed between the parties be signed by or on behalf of each party When the tenant exercises the option by giving notice to the landlord, that act is simply a unilateral trigger for the obligation to grant the lease. Accordingly, a valid exercise of...

Call options over land: formation, exercise, pricing mechanisms, perpetuities, registration, third-party protection and tax (England and Wales)

An option agreement is a contract of sale and must satisfy section 2 of the Law of Property (Miscellaneous Provisions) Act 1989. Accordingly, it must: be in writing set out or incorporate every term expressly agreed by the parties be executed by, or on behalf of, the parties By contrast, a trigger notice merely activates the option and is not itself a sale contract. As a result, the trigger notice need not bear both parties’ signatures. Exercising the option Call option agreements are interpreted strictly, and the option may lapse if the holder does not exercise it in the correct manner. Time limits Typically, the option will stipulate that the grantee must exercise it within a defined period (see Practice Note: Option agreements—land—the need for a long-stop date). If it is not exercised within that window, it will lapse because time is of the essence—this will be implied even if not stated expressly...

This Practice Note summarises Bermuda trust law at a high level and signposts its distinctive characteristics, including expansive reserved powers rules, codified Hastings Bass measures, and adaptable perpetuity provisions.
